ATP TREVOR JONES, OF GI-ZICAGO, ILLINOIS, ASSIGNOR T0 AMERICAN STEEL FOUNDRITIS, OF CHICAGO, ELLINOIS, A CORPORATION OF NEW JERSEY.

ANCHOR.

Application filed May 1,

To all whom. it may concern Be it known that 1, Ar TREVOR Jones, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Anchors, of which the following is a specification. I

This invention relates to anchors.

Generally speaking, there are two types oi anchors, one known as the stock anchor, in which the shank of the anchor has no relative movement with respect to its crown or head, and the other one known as the stockless anchor, in which the shank has a relative movement with respect to its crown or head. It is to the latter type of anchor that my invention has particular application.

The main advantages of the stockle'ss type of anchor over the other type are the ease.

of stowing away the anchor on the ship, and primarily in that the stockless type of ancho has two flukes for simultaneously engaging and hooking into the bottom of the sea for holding firmly.

The one disadvantage of the stockless anchor is that the flukes thereof are a little slow in hooking into the bottom of the sea after reaching same.

Accordingly, one object of this invention is to overcome this disadvantageous feature in a simple and eflicient manner.

Another object is to provide a stockless anchor adapted to meet all the requirements for successful use.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in which- Figure l is a front elevation of an anchor embodying my invention;

Fig. 2 is a side elevation of the same anchor;

Fig. 3 is a fragmentary side elevation of the same anchor, a portion oi"? the head being in section, and showing the shank in vertical position, with the flukes at an angle of 45 with respect thereto, one of the two positions taken by the parts of the anchor as the anchor is beinglowered and raised; and,

Fig. 4 is a side elevation of the same anchor, a portion of the head being shown in section, and showing the shank locked to the head of the anchor for causing a quick gripping action of the anchor when passed into Specification of Letters Patent.

engagement with the bottom otthe sea, the position shown being that which is assumed after the head of the anchor has reached the bottom of the sea and the shank having moved downwardly a certain predetermined amount from itsvertical position.

lhe various novel features of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings,

it will be noted that I have shown a stockless type of anchor including a head 10 and a shank 11, the latter being pivotally connectedto the former by means of trunnions l2 Xtending laterally from the shank and cooperating with bearing portions within the head. The inclined walls 13 01": the head form stops for limitingthe relative movement between the shank 11 and head 10. Preferably the maximum relative movement between said parts is about 90", there being a 45 swinging movementto either side of a central alined position of the head and shank. The head. 10 is provided with two flukes 14 which are the ground engaging or gripping members. Thehead is also provided with oppositely and laterally extending projections 15 at the base of the flukes to cause the fiukes to assume a digging or gripping position when the head of the anchor rests upon the bottom of the sea, as shown in Fig. l. However, as mentioned hereinabove, the stockless type of anchor is a little slow in digging into and gripping the bottom of the sea in spite of the inclination given to the flukes by the projections 15, as shown in Fig. 4. To overcome this disadvantageous feature and to cause a quicker gripping action of theflukes of the anchor, I have provided means whereby the shank of the anchor will become locked with respect to the head thereof at the proper point so that the weight of the shank, together with the weight of at least a portion of the chain, will act in a manner to increase the dipping or gripping action of the flukes of the anchor.

. As shown in Fig. loi the drawings, the shank 11 of the anchor is locked to the head 10 thereof by one of the two locking mem bers 16 having a hooked portion 17 which is in locking engagement with a shoulder 18 formed on the head of the anchor. The locking members 16 are pivotally connected on opposite sides of the shank 11 on a pin 19 extending throiwh the shank and through the member-s16. 4 ach of said locking members 16' is provided with a wei hted portion 20 for holding the hooked portion 17 in a position to hook over and remain in hooked relationship with said shoulder 18 as the shank swings downwardly from the vertical position to the position shown in Fig. 4:, and also forpermitting the hooked member 16 to'move out of locking engagement with the especially true in view of the fact that the weight of the shank 11, clevis 22 and chain 21 act through a relatively long leverarm, It will be understood that the shank 11 may be locked to the other side of the head by the associated gravity actuated hook member 16 in a manner similar to that shown in Fig. 4: of the drawings.

It is my intention to cover all modifications falling within the spirit and scope of the following claims.

I claim:

1. A stockless anchor including a head, a shank movably connected thereto, and means for locking said head and shank in a given relative position for creating a gripping leverage causing a quick gripping action of the anchor.

2. A stockless anchor including a head, a shank moi-ably connected thereto, and means for automatically locking said head and shank in a given relative position for creating a. gripping leverage causing a quick gripping action of the anchor.

3. A stockless anchor including a head, a shank movably connected thereto, and gravity actuated means for locking said head and shank in a given relative position for causing a quick gripping action of the anchor.

4. A stockless anchor including a head, a shank movably connected thereto, and means carried by the shank for locking said head and shank in a given relative position for creating a gripping leverage causing a quick gripping action of the anchor.

5. A stockless anchor including a head, a shank movably connected thereto, and members mounted on opposite sides of the shank for locking said head and shank in a given relative position for creating a gripping leverage causing a quick gripping action of the anchor.

6. A stookless anchor including a head, a shank movably connected thereto, and oppositely extending members for engaging opposite portions of the head in given relative positions for creating a gripping leverage causing a quick gripping action of the anchor. V

7. A stockless anchor including a head, a shank movably connected thereto, means for locking said head and shank when they are in certain relative positions for creating a gripping leverage causing a quick gripping action of the anchor, and means for unlock ing said head and shank.

8. A stockless anchor including a head, a shank movably connected thereto, means for automatically locking said head and shank when they are in certain relative positions for creating a gripping leverage causing a quick gripping action of the anchor, and means for automatically unlocking said head and shank. V

9. A stockless anchor including a head having flukes, a shank pivotally connected tosaid head, and means for looking said head and shank when the flukes have assumed a substantially horizontal position for creating a gripping leverage causing a quick gripping action of said fiukes.

10. A stockless anchor including a head,

ashank pivotally connected thereto, and means for locking sald head and shank in a given relative position when the shank has moved from a vertical position a predetermined amount.

, 11. A stockless anchor including a head,

' a shank pivotally connected thereto, and means for locklng sald head and shank 111 a.

given relative position when the shank has moved from a vertical position a predetermined amount and -tor unlocking said head and shank when the shank has moved toward a vertical position from a locking position.

12. An anchor including a head having a shoulder portion, a shank pivotally connected to said head, and a pivotally mounted hook carried by said shank for engaging said shoulder for locking the head and shank in a given relative position for causing a quick gripping action of the anchor.
